There are some incorrect uses of mathematical terminology and typos in previous papers. We rewrite them precisely here.

In Lu, Wenlian, Chen, and Tianping (2008), we studied the following class of delayed differential equations:
where di(t), aij(t), Ii(t), , are some functions; , , are some nondecreasing discontinuous functions for any , dKij(t, s); and , are Lebesgue-Stieljies measures with respect to s.

We have noticed some misuse of mathematical terminology in this previous letter, and rewrite them precisely here.

The following paragraph is from that letter (pp. 1075–1076):

weakly converges to on space .

is dense in the Banach space ), which is the conjugate space ). Therefore, for each , we have
By the uniform essential boundedness of...
